Castilleja disticha
Castilleja linariifolia
Castilleja disticha is limited to the central and southern Sierra Nevada. Although similar to C. applegatei and C. martini, C. disticha is distinctive and unique in its long, colorful, and highly exserted corollas with the beak exceeding the tube in length, calyces more brightly colored than the often unlobed bracts, and tall, strongly distichous growth form.

Castilleja linariifolia is widespread in the western United States and is important to Native Americans as a source of dyes and for medicinal and ceremonial purposes (D. E. Moerman 1998). It is the state flower of Wyoming. Castilleja linariifolia is closely associated with, and undoubtedly parasitic on, the roots of sagebrush, Artemisia tridentata. The bracts are usually red to red-orange, with uncommon yellow-bracted variants. On the eastern slope of the Sierra Nevada in California, most populations have pink-purple to magenta bracts, and at least one population has almost pure white bracts. Plants associated with hot springs in the Ash Meadows area of Nye County, Nevada, are unusually tall and have somewhat fleshy leaves. Castilleja linariifolia stems are usually glabrous, but pubescent stems are sporadic across its range. However, in the Mt. Charleston area of the Spring Mountains, in southern Nevada, most plants are pubescent, ranging from an inconspicuous layer to a fairly dense and obvious indument. These plants have been called forma omnipubescens Pennell. Elsewhere, especially in central and northern Arizona, individuals with short-pubescent stems are intermingled with more typical plants. In addition, late-blooming forms associated with hot spring sites in the eastern Mojave Desert are particularly thick-stemmed and vigorous. Hybrids between C. linariifolia and C. scabrida are known from Garfield County, Utah. Castilleja linariifolia is parapatric with the similar C. wootonii in central New Mexico. Castilleja linariifolia is reported to hybridize with C. chromosa, C. flava, and C. miniata. A possible hybrid with C. septentrionalis was named C. ×cognata Greene.
